"Dombrovskiy was released from his post at a Constitutional Court session following his resignation request," Ivan Avramov said.
A pro-presidential judge in the 18-member Constitutional Court, which is looking into President Viktor Yushchenko's decree to dissolve parliament and call early elections, Dombrovsky was reported to have already tendered his resignation April 4, but was denied it.
Avramov said Valery Pshenychny, who was reinstated as a Constitutional Court judge by a court decision May 16 after Yushchenko's ordered his dismissal in late April, had been appointed acting chairman.
Yushchenko disbanded parliament, dominated by Prime Minister Viktor Yanukovych's supporters, in late April and called snap polls, accusing the premier of "usurping power." Yanukovych earlier opposed polls, but eventually agreed.
But the factions have not yet coordinated laws to allow the vote, or its date. They had earlier planned to announce the date on May 16.
